Sounds good to me - America's spent the last hundred fucking years focusing on everyone but its own.
Fuck South America, fuck Africa, fuck Asia, and especially fuck Europe. There isn't a single country in the world that hasn't spent the last several decades endlessly chiding the US for interfering in the affairs of other parts of the world while simultaneously sticking their grimy hands out for gibs. Fuck them all.
Africa wants westerners to fuck off? Fine by me, let China strip mine and sterilize the continent if they want. Not my problem.
Europe wants us to pull all our troops and resources? Fine by me, we've been subsidizing their fucking smug welfare state for 75 years, let them pay for their own defense.
Middle East wants the US to stop getting involved in shit? Fine by me, let the goatfuckers go back to killing each other. If we go back to building fission plants in 20 years we won't even need their crude anymore.
Let the rest of the world take care of itself and let the US focus on its own.
